Vise



Oct. 3, 1939. R. L. RAMSEY VISE Filed April 14, 1958 A iiorneys PatentedOct. 3, 1939 UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates broadly to an improved work bench orsimilar vise and has reference in particular to the construction of thecomplemental or companion jaws, these being novel in that they are eachformed with a rectangular shaped body having flanges at the four edgesthereof, the flanges forming gripping parts of different types.

Admittedly, the broad proposition of interchangeable and multiplepurpose work gripping jaws is in no sense broadly new in the art andtrade. It follows, therefore, that my primary aim is to generallyimprove upon known, patented and marketed constructions, through theadoption and use of relatively adjustable'clamping units, these havingespecially constructed shanks carrying manually regulated and adjustablework engaging plates or grips, the grips and shanks coacting to providediversified utility so as to increase or multiply the range of functionsin a comparatively simple vise construction.

Briefly then, my object is to adopt and utilize a vise structure whoserange of utility is such as to permit effective and reliable clampingand holding of many different styles and classes of objects such as flatfaced rods, circular and partcircular machine elements, tools of variouscrosssectional shapes as well as soft surfaced elements of wood and thelike.

Other features and advantages will become more readily apparent fromthefollowing description and accompanying illustrative drawing.

In the drawing:

Figure 1 is an elevational view of a vise embodying the features andadvantages of the present invention.

Figure 2 is a fragmentary detailed view showing one of the supportingshank members and a detachable jaw member cooperable therewith.

Figure 3 is a section, on an enlarged scale, taken approximately on theplane of the line 3-3 of Figure 1 looking in the direction of thearrows.

Figure 4.- is an enlarged fragmentary perspective view showing thespecial configuration of the jaw member supporting shank.

Figure 5 is an enlarged transverse or cross sectional view taken on theplane of the line 5-5 of Figure 1.

By way of introduction to the detailed description, it is to be pointedout that I am not especially concerned with the supporting bench, baseor other relatively fixed supporting means in general. In the drawing,however, a part of the support is denoted by the numeral 9 and therespective relatively stationary and movable clamping or jaw units,associated therewith, are differ- I entiated by the numerals Ill and IIrespectively. Any suitable adjusting means I2 is employed andappropriate clamping means I3 is also utilized. The sleeve members M ofthe units Ill and II coact with a complemental assembling bar or rod 15which also is of no particular moment. Perhaps, however, novelty may besaid to reside in the provision of the tubular bodies 14 in conjunctionwith the complemental converging shanks I 6. That is to say, the shanksincline toward each other at approximate 25-degree angles, and eachshank as shown in Figure 4, has a flat faced plate backing surface I!and a retention shoulder l8 as well as a threaded bore or hole l9 toaccommodate the shank of the clamping and assembling bolt. It will alsobe observed in Figure 3 that the threaded bolt hole is formed with acounter-bore, this being enlarged in diameter as shown to advantage inFigure 3, and as indicated at the point 2|. The counterbore serves toaccommodate the abutment disk 22 carried by the clamping and assemblingbolt 20. The tool-end 23 terminates within the confines of the shieldingor protective socket 2| where it is nevertheless readily available tofacilitate turning with a socket wrench or the like.

These especially inclined bored shanks l 6 serve to accommodate theduplicate companion adapter grips or plate units 24. The parts 24 arethe same in construction and a description of one will suffice for both.

As brought out to advantage in Figures 5 and 6 each part 24 comprises asubstantially rectangular flat plate 25 and this is provided alongopposed parallel edges with outwardly diverging fianges 26 and 21respectively. The work or tool engaging face of the flange 26 is knurledor milled as indicated at 28. This provides an antislipping grip on thework (not shown). The corresponding face 29 of the other flange 21 ispreferably plain whereby to render it sufficiently smooth to maintain anon-marring grip on wooden or equivalent compressible objects andbodies. That face of the plate resting against the backing surface I lis perfectly smooth and flat and it will be observed that at the centerof the plate there is a screw threaded bolt hole 30 to accommodate theshanks 20 and to permit the plate to be turned around this as an axis,that is, revolved through an orbital path to bring the various workengaging features into the most advantageous work gripping position. Itwill be observed that the plate also carries marginal laterally directedparallel flanges 3| and 32. The

end portions of the flanges 3| and 32 are beveled outwardly as indicatedat the point 33 to provide What may be called auxiliary work engagingfaces. Primarily however, the flanges 3i and 32 are provided withcentrally disposed V- shaped notches 34 and 35 respectively, and theseare roughened or milled to provide additional selectively usable jaws orgrips. It follows, therefore, that the structure is characterized by apair of jaw units movable toward and from each other and havingconverging shanks, the shanks being shouldered and made to accommodatethe clamping bolts which in turn serve to maintain adjustably in placethe adapter plates. These plates are provided with marginal flanges andthe flanges have their edge portions so designed as to provide thedesired selectively usable work engaging element to accommodate thevarious shaped tools and machine elements adapted to be held between therespective jaws. It Will be observed in Figure 1 that while the platesassume diverging or converging angular relationship, as the case may be,this angularity of parts brings the respective flanges into planesparallel with each other, that is, at proper angles to satisfactorilygrip the object or objects (not shown), adapted to be held therebetween.

Attention is also directed to the advantage derived from the adoptionand use of the fiat surfaced supporting shanks having shoulders coactingwith the flanges on the adapter plate Whereby the plates can be slightlyloosened through the use of the clamping screws as just surhciently toallow clearance between the plates and shoulders to facilitaterevoivable adjustment whereby to bring the desired set of clampingflanges into play. Moreover, as before pointed out, the toolend of theclamping screw is adequately housed within the limits of the socket 2|for protection and to avoid accidental loosening thereof. Fur--thermore, with jaw faces or plates of this type, pip-es and rods andother parts can be satisfactorily clamped in position to besatisfactorily treated or worked on in both vertical and horizontalpositions. Thus, it will be seen, that the novelty resides, structurallyspeaking, in the parts separately and collectively, and the claim is tobe interpreted accordingly.

It is thought that the description taken in connection with the drawingwill enable a clear understanding of the invention to be had. Therefore,a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown anddescribed, it is to be und rstood that minor changes coming within thefield of invention claimed may be resorted to if desired.

1. claim:

A vise of the class described comprising a pair members each providedwith a shank portion and said shank portions converging upwardly, theadjacent faces of said shank portions being flat and terminating in asloping shoulder at its inner edge, a pair of jaw members each ofrectangular shape, means for pivotally connecting the central portion ofeach jaw member to a shank with the inner face of the rectangular shapedpart resting on the flat face of the shank and each rectangular parthaving flaring flanges extending from its edges, with one flange adaptedto engage the shoulder of the shank, the outer edges of the flangesforming gripping parts, said gripping parts being oi different types.
